Benefits of technology

[0009] The Working Theory: when the clip-on is put onto the frame, the magnetic coupling parts firmly adhere to one another. When taking off the clip-ons, only a little force is needed to overcome the magnetism, and the clip-ons can be taken off conveniently. Furthermore, the contact points of the magnets are remote from the free ends of the bridge-carrying arms, i.e., especially higher than such ends and forwardly of such ends, so as to not affect the adjustment of the bridge.
[0010] The advantages of the new model: (i) it is easy to wear and take off the clip-ons and convenient to adjust the positions of the bridge. Hence, users will find it comfortable and convenient.

Problems solved by technology

Although it is convenient to attach or separate the clip-on, owing to the resistance generated from the magnets, adjusting the bridge is difficult and will make users uncomfortable, and makes it harder to adjust the glasses as well.

Embodiment Construction

[0018] Depicted in FIGS. 1 and 3 are conventional eyeglasses A, the frame of which includes an eye rim 1 having a pair of rearwardly projecting arms 2. A swivel 3 is disposed at the free end of each arm 2, and an adjustable nose bridge 4 is attached to each swivel.

[0019] The sunglass clip-on C shown in FIG. 2 comprises a tinted glass or plastic eyeglass-covering portion 10, a pair of legs 8 each including a generally horizontal segment 8a projecting from the eyeglass covering portion, and a downwardly extending segment 8b which carries a head 7. Each head 7 carries a first magnetic coupling part 6 which is adapted to be magnetically coupled to a second magnetic coupling part 5 affixed to the rim 1 and from which a respective arm 2 extends (see FIG. 5). Alternatively the part 5 could be next to the arm 2. The first coupling part 6 could comprise a strong magnet and the second part 5 a magnetizable material (e.g., a suitable metal), or vice versa. Alternatively, both parts 6, 5 could...

Abstract

A sunglass clip-on includes an eyeglass-covering portion from which a pair of legs extend rearwardly. Each leg includes a generally horizontal segment and a downward segment. A head is carried by the downward segment of each leg and each head includes a magnetic coupling part having a forwardly facing surface magnetically attachable to a rearwardly facing surface of a magnetic coupling, art affixed to an eyeglass frame at a location remote from an adjustable bridge of the eyeglasses

Description

TECHNICAL AREA [0001] This invention relates generally to eyeglasses, and in particular to clip-on sunglasses. TECHNICAL BACKGROUND [0002] Clip-on sunglasses have been found on the market long ago. People walking in the sunlight with these sunglasses can protect their eyes well, so it is welcomed by customers very much. One of the types of clip-ons that can be found is magnetic clip-ons. The magnetic connection point between the frame and the clip-on is at the end of the arms of the bridge on the frame. Although it is convenient to attach or separate the clip-on, owing to the resistance generated from the magnets, adjusting the bridge is difficult and will make users uncomfortable, and makes it harder to adjust the glasses as well. [0003] The purpose of this invention is to provide a magnetic sunglass clip-on which is convenient to be clipped onto and taken off from the eyeglass frame, while making it easy to adjust the position of the bridge on the frame, so that users will find it...
